Developer tools built for real incident work
Bug Days is an open-source collection of small, focused tools for the awkward jobs that interrupt a developer’s day: reading a JVM thread dump, inspecting an unfamiliar certificate, testing a SOAP operation, documenting a database schema, or rescuing a terminal table for a spreadsheet.
How the tools work
Parsers, converters, visualizers, and generators execute in the browser. Files and pasted text are not uploaded to Bug Days. Tools that make network requests—such as the SOAP, REST, SSE, and WebSocket clients—connect to the endpoint you enter. A share link is an explicit action and may contain compressed tool input, so it should be reviewed before sending.
Built in public
The implementation is available in the public Bug Days source repository. That makes the privacy model inspectable and gives developers a direct place to report a parsing edge case, suggest a diagnostic, or contribute a fix.
What we optimize for
- Useful output within seconds, without an account or installation.
- Clear limitations instead of security or diagnostic claims the browser cannot prove.
- Exports that fit the next step: CSV, Excel, JSON, Markdown, SQL, PEM, or printable reports.
- Examples grounded in the formats developers encounter in terminals, logs, IDEs, and enterprise systems.
